Poor idea! Imagine having a bussy day,lots of calls. Now a potential customer calls and you cant spent a few min on the phone because your almost out of time. Not very profesional. Dont do it to yourself. Besides that I think prepaid phones cost about twice the price per min as a regular plan.

It's not the cellular to be sure, plenty of us use them exclusively, but most of us (like myself) have a limited calling plan that is powerful enough yet economical.

I think I get 600 anytime minutes and 3k weekends / evenings plus free long distance and free roaming for $40 / month... I mean, it don't get much better than that, just be sure you get at least 400 anytime minutes and you need to watch them until you know you won't go over (or get a bigger plan).

No way I'd go with a prepaid, it's too fly-by-night, even if the customer never finds out, the whole idea kinda stinks of it.
That, and it's too expensive. No, I am firmly against it, if for no other reason than it raises your communication costs sky high, and running high costs are no way to run a business.

My tip is start saving, you should have at least 5 thousand dollars spare cash starting out, it's a lot easier that way.
It may take you 2-3 years, you may even have 10 or 20 thousand after that, but you'll appreciate the money a lot more.
Credit is a bad idea, even if you got it, once again it drives the cost through the roof (unless you can get 0% interest, but even then, what if you can't make the payments...), not a good idea for at least the first 3-4 years.

i use a cingular go phone pay as you go, i used to have a tracfone. I like them both, but when i upgraded to a new phone i went with cingular, the plan i have is .10/min with a $1 access charge on days i use it. I don't use it enough to justify the kind of monthly play i would like. i get free cingular to cingular(and tracfone bounces off cingular, so i can call tracfone customers for free) It lets me know when i am down to $5 and i go and put more on. when i get my new truck, i'll get the verizon plan with onstar, but until then, i'll use my prepaid.
